Referrin ings, and rst to Figs. 1, 2, 3, 4, 5, 7 and 8, the main base member lof the machine comprises a air of side frames 1 and 2 rigidly connected) in front by a transverse plate 3, and in the rear of said base plate by a plurality of cross-bars 4. Said side frames are provided above with guide ralls or. ridges 5 and 6 respectively, upon which 1s slidably mounted a carriage 7 provided with rooved slides 8 and 9. As shown best in gigs. 5, 7, and 8, the side frames 1 and 2 are provided respectively with feed racks 10 and 1 1, with which mesh the spur gears 12'and 13 for feeding the carriage along said rack in a manner to be hereinafter referred to. Mounted upon the carriage 7 is a horizontal grooving device which preferably consists of an endless chain 14 provided at intervals with grooving tools 15 projecting at differ'et angles from the endless chain 14, as shown in Fig. 5. For suitably mounting the endless chain 14 so that it will stand up under the heavy work which it is calledv upon to perform, a housing 16 :lorv the endless chain extends :on either side of the carriage and across the front, said housing being provided with a T-slot 17 openinglatera-lly. Projecting through the lateral ogienixlilg( of the housing 17 are-a plusha s 18 for mounting the tools or cutters 15 upon the endless chain 14. As

shown best in Fig. 4, the endless chainl 14 receivesl its power from a driving sprocket 18 keyed to a vertical shaft 19, which shaft derives its power in a manner to be hereinafter pointed out. In order tto provide means for regulating the tension on the endless chain 14, across rail 20 connecting the rear ends of depending housing 16 .is provided with-*a depending lug 21 for supporting a nut 22. Threaded within said nut 22 is an adjusting screw 23 upon which. is keyed a worm wheel 24 driven by a worm 25 carried by an adjusting shaft 26 l'extendin transversely 'across the carriage and pro vided with squared ends 27 for the reception of a key lever not shown on the drawings.. At the forward corners of'the lrousing 16 are provided a' pair of bearing blocks -28 of hardened steel, which are secured in position in the chain housing in any suitable Ina-nner, At the rear corners of the housing similar bearing blocks 29 are provided, about which thechain 14 p aes on its way' to and from the sprocket 18. By means of the employment of the blocks 28"in the forward end of the .carriage-7 it is made possible to bring the forward end of the end more specifically to the draw-` l'or shields 37 (see Fig.

less belt conveyer to be herinafter referred to, nearer to the wall of material which is to be operated upon so that the excavating action of the machine is facilitated and its eiiiciency reatly cnhanced.

The en ess belt conveyer shown separate from the machine in Figs. 12, 13 and 14, comprises a pair. of endless chains 30, which are oppositely v-m'u'md on supporting sprockets 31., 32 carried by transverse shafts 33, 34 journaled in the side walls or upright members '35,l which, together with a web member 38, forms the chute of the conveyer. Intermediate of the shafts 33 and 34 said side walls are rigidly connected by cross bars or plates 36. Said side.walls 35 are provided with inwardly projecting ledges 8) under which is rigidly mounted the supporting web 38, preferably of sheet metal, which extends approximately from the sprocket 31 to sprocket 32, being supported throughout its length on angle irons 39. The chains 30 are slidably mounted upon the web 38 beneath the overhanging portions of the shields 37, said chains being provided at intervals with conveyer bars in the form of angle irons 40 secured at their ends to the chains 30. It will therefore be seen that as the chains 30 pass upwardly over vthe web 38, the angle bars 40 will engage coal which comes in their way and slide the same upwardly over the .sa-id web 38 to the rear of the machine. The shafts 33 and 34 may be rotatably supported within the side walls 35 in any suitable manner, but preferably by being journaled within brackets 41'rigidly mounted on the web plate 38. The carriage 7 is provided with standards 42 and 43 having projections or lugs 44 upon which the chute including' the endless belt conveyer is adapted to rest in such manner as to be readily removable whenever desired. The .endless .chains 30 derive their motion through the shaft 34 and.

cross shaft 46, which cross shaftis provided on its other end with a sprocket wheel v47 connected by a downwardly extending endless drive chain 48 'receiving power from the short horizontal shaft 49 which is driven by means of bevel gears 50 from the main drive shaftl, which in this embodiment of the invention is directly connectedv to the motor shaft of the .motor 52 (see Figs. 2 and 3). Whenever, for any reason, it is desired to dismantle the machine, the chute comprising side walls 35 and webA member 38 maybe removed bodily endless chains 30 with th'elr connections, by first removing the endless chains 45 and 48 from the sprockets'on shaft 46.

. The motor 52 has an armature rigidly laterally disposed along with the V so ' pivot 69 is provided with e'eforked extremity viii lthe shiift 57 above the geur 5G. The loweif end of the shaft. 57 is'piovided witliii driv-j ing worm 62 'meehing with e worin ivheeif;

y referring to Figs. 28 to 31, inclusive, it will be seen that the adjustments maybe so made as to vary the extent-of reciprocation of the vertical kerf cutters 80 while keeping the lower limit of movement thereof substantially the same for every adjustment. In order to accomplish this,v the nut,179 should be loosened so as to permit free movement of the collar 184 of the journal pin 104 over the boundaries of the slot 103, and to likewise permit .free movement of the Washer 178. Now, it will be' evident that-if the a`rms 77 are held in such position that the vertical kerf cutters will be kept'clear of the framework of the' machine, the desired adjustment may be made by turning the screw 108 in the sliding blo'ck 105 by applying a'wrench to the squaredI hea 180. The arms 77 when freed by loosenin the nut 179 may be held in their lowermost positions by means of props. lVhen the nul: 179 is loosened and the sliding block 1(15 moved upwardly as viewed in Fig.v 30, the arc of swing of the arms 77 will be shortened, while if the sliding block 105 is moved downwardly the arc of swing will be lengthened. This is obvious u on a comparison with Fig. 28, from which 1t will be seen that the movement of the sliding block 105 changes the radius of the laterally extending journal bearing 181 from th center of the gear 107, which is pivotally supported at'185 in the bracket 186 of the main frame o f the machine. It should be noted that the jojilrnal bea-'ring 181 is rigidly connected to the sliding block 105, while the journal sleeve 104 is freely rotatable on the journal bearingi'181 when the nut 179 if loosened. 'By holding the arms 77 at the de ired lower limit of travel and loosening t "e nut 179, the block 105 together with the journal bearing 181 and sleeve 104 may be moved u'pto the desired position.

. in p'ositionrmly clamping the `collar 184 f Aa cotter pin 182 may be arm 102, but Athe journal `181 is sti and washer\1`78 against the Asurfaces bounding the slot 103. The sleeve 104 will then be held rigidly in position relativel to the lil freely rotatable in the sleeve 104 to the extent necessary when the gear 107 rotates.. The rotary motion of the journal bearing 181 will produce a 'reciprocatory motion of the pivotalfpoint 183. This will`produc e a reciprocator'y swing of the arms 77 and also thevert-ical kerf cutters 80, the lower limits of movement-fof the latter being always the same and in accordance 'with 'the adjustments made. proper position on the journal bearing 181m, inserted through the .is provided with a To keep the collar 104 in' journal 181, as shown in (see particularly Figs. 7

and 9). Coaxially and rigidly connected with the s ur gear 116 is a cam 118 which is suitably isposed to impinge a collar 119 carried by the pick rod 96, so that vas the cam v118 revolves about its axis, the pick rod is forced rearwardly 'against the action of the spring 99 and in rearmost position is released by the cam 118 and driven forwardly by the spring 99 into the coal or other material to be mined. In order to Widen the range of action of the automatic pick, the pick rod 96 is made oscillatable u on lts own axis and upon itsrearward en is provided with a' hand lever 120, which, while it is freely rotatable about the rod 96 is provided with a spring clutch lever 121, to..-

the depending end of which is pivotally connected a locking pin or bolt 122 (see particularly Fig. 25) slldably mounted in a cylindrical hole in the hub portion 123 of the hand lever 120. Keyed to the pick rod 96 and interposed between the hub portion 123 and the rearmost bearing 97 is a sleeve 124 provided with a radial arm 125 (see particularly Fig. 24). The extremity of the radial arm 125 is rounded or provided with a ball 126 which is adapted to engage in a groove 127 see also Fig. 27) ecentrically disposed in the side face of a gear 128 which latter journal pin 129 projectingv laterally therefrom, which pin 129 is journaled in the outer end of a bracket 130. The bracket arm 130 is preferably an integral laterally projecting portion of the rearmost bearing 97. Rigidly mounted on the rearmost bearing block 97 is a second bearing block or pedestal 131 (see particularly `igs-. 9, 22, 23 and 24) within which is journaled a short shaft 132 provided on one end with a sprocket wheel 133 over which` passes an endless chain 134 supported atits other loop end by av sprocket 135 keyed to the short shaft upon which the spur gear 116 is mounted (see Fi 7). By this means power is imparted to t e short shaft 132 and may be transmitted to the gear 128 for automatlcally rocking the pick rods 96 by al sleeve gear 136 which is freely rotatable on'the shaft 132 and slidable therealong. Said shaft ,132 is provided with a tapered enlargement'137 which is adapted to act-'as a clutch element, the gear 136 being-provided xin its side face with a similar tapered surface 138 which may be locked with the tapered eng; largement 137 when the sleeve gear 136 is reclprocated along the shaft i132. For this purpose ashifting lever 139A is "employed,

amazes which may be pivotally mounted on the vmarriage at any-suitable point, and is provided above :with a bifurcated portion 14() with suitable pins engaging'in a groove 141 in the cylindrical wall of'a collar 142 rigidly connected with-the sleeve gear 138. A ha ndle 143 formed as an extension of one of the forks of the bifureated portion 140 serves as convenient means for shifting the lever 131). From this-alescription-it will 'be seen that when the level- 131) is shifted,v the sleeve gear 136 isl moved over into engageu'lent. with the tapered projection-13T and has motion translzo mitted thereto which it in turn transmits to the. gear 128, so that as .said gear 12H ro` fates', the groove or alot.l 12T therein oscil lates on the radial arnl 12:1; and thus causes "the pick rodllti to automatically oscillate,

upon its own axis .without in any way interfering with its other i'x'lovenients,

Referring noweinore especially to Figs. 1, 2, 3; 32, and B4, the; preferred embodiment of. a loading conveyer'is shown and `'comprises a base member and an endless chain conveycr. .Said base' member is c0n` structed of side fra-nies 144 and 145 rigidly connected in anylsuit'a-ble manner and provided at one end with a Hat bar or plate 146l connecting'the-ends of said side'frames.
